LIC5A-Urban+Ecology

= Long Island Creek Site 5A = = Urban Ecology =

USDA Tree Risk Assessment was carried out once at every site during the sites' monitoring period with the intention of evaluating the urban ecology area adjacent to the waterbody. The objective of this assessment is to evaluate defective parts in selected trees and their respective risk of failure and hazard. Trees at Long Island site 5A are predominantly healthy and have a low probability of target. Overall, the most common defects were Poor Tree Architecture: Leaning Trees and Root problems caused by erosion, specially those trees near or on stream banks. Two of the selected trees are dead though their probability of target is low as their locations are of occasional use and their lean away from local houses. As the table above indicates, trees risk rating range from 3 to 5, and the average risk rating is 3.4.

__**Visual-Biological Factors**__
The observed wildlife at Site A consisted of mammals, crustaceans, and the resident fish in the creek. The mammals were deer as evident by their tracks, and were the only ones observed. The crustaceans were crayfish which were only seen minimally. Fish were abundant in the creek, ranging from small (1-2") to medium (3-6") in size. The larger fish were found primarily around the pool located upstream, while small schools of the smaller fish could be found throughout the area. There were no barriers to fish movement or any aquatic plants found in the study area with the expection of small patches of brown and green algae. Both brown and gree algae was found as a light coating on the rocks, primarily near the riffles. There was no filamentous or free-floating algae found at the study area. This area of the creek was heavily shaded from the sun, with approximately only 20% of the study area receiving direct sunlight.
